OIL BURNER.

Application filed. August 29, 1921. Serial No. 496,376.

To all whom t may concern.'

Be it known that I,WARD T. BARKER, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a'. certain new and useful Improvement in Oil Burners, of which the following is a complete specification.

The present invention relates to oil burn-l ers for furnaces, and one ofthe lprincipal objects in view is to provide an improved type of burner making use of a steam spray in conjunction with the yoil discharge to insure the effective breaking up and Vaporizing of thevoil at the discharge point of the burner. Accordingly, I have devised an improved burner of this character in which a steam jet is provided at a location imme# diately adjacent to the oil discharge port, and of a size ample to answer all the requirements of said oil discharge port. 'A

Y In this connection it is also soughtto provide an improved adjusting means Vfor regulating the sizel of the respective oil ,and steam discharge ports, and operating to si-v multaneously regulate the same according to requirements, while tive size between the two ports.

,In carrying out this the improved burner, I provide separate oil and steam chambers having a rotatable member forming'the partition betweenthe chambers, and so arrangedv thatthe oil and steam discharge ports are regulated in size by the mere rotation of said partition element.

With these and various minor objectsinview, the invention will now be Adescribed by reference to the accompanying drawing,

illustrating one form of construction which I have devised for embodying the proposed improvements, after which the novel features therein will be and claimed.

In the drawing- Figure 1 is a side elevation, illustrating a burner vconstruction embodying the improvements;

F lgure 6 is a detail section taken on the Y line VI-VI of FigureY 5;

Figure 7 is a the rotatable partition 'element' which separates the oil and Figure 8 is a vertical sectional view, showing the by-pass connections between the oil' and steam lines leading to the burner.

Referring now to the'drawing in detail, this shows the improved burner device as comprising substantially similar inlet connections 10 and l2, the formerY being fitted with `an oil supply pipe 14, andthe latter h'avinga steam supply pipe 15, vaslshown in Figure 1. Joiningthe inlet; connections 10 and 12 is a bolt 16, .which serves asa common axis of adjustmentfor an oil chamber element 17 ,Y a' steam chamberv `element. 18, and also a rotary partition element 19 interposed between the elements4 17 and 18 and therebyv serving'to separate the oil'discharge chamber 20 from the steam discharge chamber 21, las will be found'clearly illustrated in Figure 3. Each inlet connection is provided with an undercut passageV 23, one of which passages vcommunicates vwith the chamber 20 through an` arcuate opening 24 in the element 17, whilefthe other passage 23 communicates with the chamber V21 through aA similar arcuate opening 24 in the element 18. Each of the' elements 17 andv 18 is provided Vwith 25'passing through the corresponding opening 24:l and into engagement with-the corresponding inlet connection 10 or 12, whereby either ofthe elements 17 or 18 may be rotated aboutl theaXis of the bolt 16 and clamped in any` position of adjustment, for a purpose hereinafterfexplained.

At the front of the burner 'are provided a 'steam jet opening 8O communicating with the steam discharge chamber 21, and also an oil discharge port 31 communicating .with the interior of the oil chamber 20. These steam discharge chambers;

va clamping* screw perspective viewshowing K Y Gil ' '18y and proceeds opposite directions. In the case of the elements 17 and 19 for producing the discharge opening 31, the spiral cut starts with a shoulder 32 on the element 17 and terminates with a shoulder 33 on the partition element 19, so that the discharge opening 31 is produced by relation rotation of the elements 17 and 19, thereby` separating the shoulders 32 and 33, and thereby also regulating the size of the oil discharge opening 31, according to the extent of separation of said shoulders 32 and-33. In the case of the steam discharge opening 30, thespiral cut begins with a shoulder 34 on the element in a spirally opposite direction (as regards the first mentioned spiral out), and terminates inia similar shoulder 35 Jformed openingr30 is formed, .and the size thereof regulated, in the same manner as the oil discharge opening 31.' From this -it will be seen that after the relative size or the openings 30 and 31is initially'` determined, the rotary adjustment'o the partition element l" 19 will servefto simultaneously regulate the size of both of said openings, increasing or diminishing the same,- according to requirements.

Associated with the pipe connections 14 and 15 is a 1oy-pass arrangement, whereby oil received romfa lower level the steam supply `may be by-passed around the steam so -as to `feed the oil to the top chamber of the burnerfand allow the steam to be passed tothe lower chamber 21 of the burner. Referring-to Figures 1 and 8 of the drawing,it will be noted that the pipe 14l communicates'with -a'passage 40 of a by-pass'head 41, while-the steam pipe 15 communicates withv a passage 42 in said head member 41 (see Figure 8). Attached to the outer ends of the head member 41 isa pair-of nipples 43 the upper one of which is `engaged by an L-casting 44, the lower nipple 43V being clamped in communication with a crosshead element45 engaged by the opposite arms of ayolre member 43 the head of which is provided with la clampingscrew 47 yengaging they boasting 44 and operating thefsame to securely clamp all the parts ofIY shown'. The cross headl member 45 communicates with fa pipe k43 provided with-a valve, (not shown) Jfor regulating the flow ot'oilto the passage `40 and thence to the burner. The L-castingf' member 44 communicates with a steamfpipe 49 fitted with a' valve 50for regulating the supply of steam tothe passage 42 and vthence tothe burner. A valve 51 is adapted to allow opening A`of the :passage-40 vvinto communication with the passagerel-2,vv whereby'fa-jet of steam` may a' befdischarged.lv through Y the oil chamber 20,1tooblow out and 'thoroughly clean; .theilatterfas"ottenlasmay be desired.

on the' element 19, so that the' than that of the by-pass structure together asA lt will thus be apparent that l have devised a simple, practical and edicient burner construction for tulilling the desired objects ot the invention. The size of the discharge ports 30 and 31 is initially adjusted, I

by rotating the parts 17 and 18 about the axis o the bolt 16, and clamping the same by means or' the clampingscrews 25 for setting the shoulders 32 and 34 at the proper relative locations for determining the correct relative size ot the oil and steam ports 31 and 30, the latter of which should be slightly greater than the former in order that the entire oil jet will be subjected to the heating and atomizing eiiect or the steam. After the initial adjustment of the shoulders 32 and 34 has been obtained 'tor adapting the burner to the grade ot oil to be used, the size of the jets may be regulated, for either increasing or diminishing the size of the ports, by rotating the partition element 19.' 'lhe described assembly of parts forms a tight burner structure, in which all the parts fit closely and evenly together and at the same time allow all the adjustments provided :tor without any chance of any seams or openings occurring except at the jet oriices 30 and 31.

lt will be understood that the by-pass construction is designed to be located outside the furnace, and enables the oil and steam lines (usually arranged with the steam line above) to be crossed in order that the steam may be supplied to the lower chamber of the burner as required for obtaining the correct burner action. rlfhe bypass head construction also enables a preheatingaction toy be exerted upon the oil low, and the position or the valve 51 allows a-blast of steam to be blown through the oil connection and discharge chamber 2O for eectively blowing out and cleaning the same.

While l have illustrated and described what l now regard as the preferred form of construction for embodying the proposed improvement-s, l desire to reserve the 'right to make such changes or modifications as may fairly 'fall within the scope oi the pending claims.
